I Am Impact!

I Am Impact! is a song by Ichirō Mizuki for Mystical Ninja Starring Goemon. It is the main theme song of Goemon Impact, which plays each time he is summoned prior to a giant robot battle. A full version of the song[1] appears on the Mystical Ninja Official Soundtrack. In Japanese versions of Goemon's Great Adventure, a modified version of the song is used to open giant robot battles in which Impact and Miss Impact fight side-by-side. A full version of the modified song appeared on the soundtrack to the said sequel. It is assumed that the song is sung by Goemon Impact himself, due to the deep voice and the game's suggestion that Impact is interested in the performing arts.

The song that appears in Mystical Ninja Starring Goemon is a clipped and slightly variated version of the song found on the Mystical Ninja Starring Goemon Official Soundtrack - only the first verse is played, likely due to the fact that the song plays a total of three times in the game before a major giant robot battle, and playing the full version would take too much time. The song is accompanied by a video of the character summoning Impact and piloting him while the camera gives the player a tour of Impact's clockwork interior.

The character blows the Triton Shell and Impact appears, pulling them into his mouth via a beam of green light. The character falls down what appears to be impact's trachea as the camera pans around the robot's body displaying his clockwork skeleton. The character is then pushed up behind Impact's eye in a chair, from where it is assumed the robot is piloted.

After the sequence, the player may move the N64's control stick in order to rotate, lower, or raise Impact's head.

A modified version of 'I am Impact' is used in Japanese versions of Goemon's Great Adventure so that the lyrics state the fact that Miss Impact has now joined the fight. Like 'I Am Impact' in the first game, the song and a similar action sequence play before each giant robot battle.
